DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to improvement of a roller for applying / absorbing liquid or for removing / cleaning liquid.

<Prior Art> Conventionally, there has been a cleaning roller as shown in FIG. There was also a paint coating roller of similar construction. They are,
The roll (a) used for each of the above purposes is fixed to a holding portion (b) that rotatably holds the roll (a). Holding part (b)
Includes a shaft portion (c) that rotatably penetrates the roll (a), and a handle (d) for pressing and rolling the roll (a) on the surface of another person. These rollers are, for example, rolls (a)
The cylindrical body (e) having an adhesive member on the outer peripheral surface is detachably mounted on the outer peripheral surface of the outer peripheral surface (if used for a purpose other than that used for application or absorption of liquid, those A cylindrical body having a member corresponding to is provided on the outer peripheral surface is used). In other words, it has a structure that can be replaced with the same one if it becomes dirty and the cleaning power decreases.

<Problems to be solved by the invention> However, while such a roller is pressed and rolled by another person, the cylindrical body (e) fitted to the roll (a) is often adhered and detached. It was

The present invention aims to solve the above problems.

<Means for Solving Problems> The roll comprises a cylindrical body (1) and this cylindrical body (1) as a core.
A roll (2) fitted inside, a shaft (3) that is axially fixed to the roll (2) and rotatably holds the roll (2), and a pressing member (8). Take.

The roll (2) has a recess (6) formed on one end surface (5) thereof. The appropriate position on the periphery of the recess (6) is the peeling part.
(7) 'is provided. The peeling portion (7) 'is a region bordered by the split (7) extending from the inner peripheral surface side of the concave portion (6) to the outer peripheral surface side of the roll (2) and has elasticity. is there. The pressing member (8) has an appropriate fixing means,
By this fixing means, the roll (2) is fixed to the recess (6) so that it can enter and exit, and the pressing member (8) has a peripheral side surface having a portion larger than the inner diameter of the recess (6). Have (10). When the pressing member (8) enters the recess (6),
A part of the peripheral side surface (10) of the pressing member (8) presses the inner peripheral surface of the recess (6) to try to spread the inside of the recess (6), and at this time, it has elasticity and split (7). By the presence of the peeling portion (7) 'having a degree of freedom in the outer direction of the roll (2) is spread, that is, raised toward the outer side of the roll (2), the inner peripheral surface of the cylindrical body (1), It is pressed against the peeling portion (7) '.

The cylindrical body (1) has an absorbing member for a liquid or the like on its outer peripheral surface.

The cylindrical body (1) has an adhesive member for removing dust on its peripheral surface.

I try to push the inside out. If the inner peripheral surface of the concave portion (6) of the roll (2) spreads as it is expanded, the diameter of the inner peripheral surface of the roll (2) may be increased, and the curvature of the inner peripheral surface may be moderate. It is only the peeling portion (7) ′ that such freedom is given. Therefore, as a result of the split (7) being spread in the radial direction of the roll, the peeling portion (7) ′
Only tries to stand up to make the curvature gentle.
Then, the inner peripheral surface of the cylindrical body (1) is pressed against the peeling portion (7) '.

This allows the cylindrical body (1) and the roll (2) to be firmly fixed to each other.

Since the outer peripheral surface of the cylindrical body (1) can hold a liquid, the liquid can be applied by using such a cylindrical body (1).

Since the outer peripheral surface of the cylindrical body (1) can adhere dust or the like, cleaning can be performed using such a cylindrical body (1).

Since the shaft (3) has the handle (4), by holding the handle (4), the rolling operation of the cylindrical body (1) for obtaining each of the above operations can be easily performed. .

<Embodiment> A preferred embodiment of the present invention will be illustratively described in detail below with reference to the drawings. However, the dimensions, shapes, materials, relative positions, etc. of the components described in this embodiment are not intended to limit the scope of the present invention to them unless otherwise specified. , It is just an example of explanation.

FIG. 1 shows an embodiment of the present invention.

Detach the hollow cylindrical body (1), which is provided with a dust-removing adsorption member such as an adhesive member or an adhesive tape, or a moisture absorbing member such as a sponge on the peripheral surface (1 '), to a separate roll (2). Attach freely. This roll (2) is cylindrical and its axis of symmetry (as a rotator) is penetrated by a shaft (3). The roll (2) is rotatably fixed around the shaft (3) as a rotation axis. One end of the shaft (3) is extended to the outside of the roll (2), and a handle (4) is extended at the end of the extension (3 ′) (extension (3 ′) of the shaft (3)). Is not limited to the bending direction as shown in Fig. 1. Of course, it may not be bent).

The other end surface of the roll (2), that is, the end surface (5) on which the shaft (3) is not provided is provided with a recess (6). End face
From the peripheral edge of (5) to the peripheral edge of this recess (6), there are splits (7) at appropriate positions. The area bordered by the split (7) is the peeling portion (7 ') described in the scope of utility model registration. The shape of the split (7) is, as shown in FIG. 1, a substantially L-shape at the peripheral portion of the end face (5). Here, the details of the purpose of the present application are as follows.
This means that the extending direction of (7) should have a component along the circumferential direction (X) of the roll (2). For example, if only the component in the direction perpendicular to the circumferential direction (X), the length of the peripheral edge of the end face (5) or the depth of the recess (6) is required with respect to the axial direction of the roll (2). Therefore, the sliding width of the pressing member (8) described later has to be secured more than necessary.

The roll (2) is formed of a material having elasticity at least in the vicinity of the split (7). Of course the roll
(2) There is no problem even if the whole has elasticity.

A pressing member (8) is fitted into the recess (6) by screwing or other suitable fixing / sliding means.

The fixing / sliding means will be described later.

As the pressing member (8) enters the recess (6),
The pressing member (8) is pressed to widen the portion where the split (7) is inserted. At this time, the cylindrical body (1) is fixed to the roll (2) by receiving the bias of the pushed-out portion. The number of divisions (7) is not limited to the number shown in this embodiment, and may be provided in an appropriate number and in an appropriate position. The peeling section (7 ') is a roll
(2) Needless to say, it is effective if a plurality of them are provided at symmetrical positions on the end face.

2 (K), 2 (L), 2 (M), 2 (N), and 2 (O) show another embodiment of the above-mentioned splitting (7). . However, the present invention is not limited to these examples, and the direction in which the split (7) extends is as described above.
It is considered that the condition of the present application is satisfied if there is a component along the circumferential direction (X) of (2). FIG. 2 (A) shows an example in which the L-shaped bending angle of the split (7) is implemented at an angle other than a right angle. FIG. 2 (B) shows a curved portion of the split (7), which is formed in a substantially J shape. The structure shown in FIG. 2 (C) is formed so as not to bend and have a circumferential component, but to extend obliquely and linearly from the end. What is shown in FIG. 2D is the second
By improving the embodiment shown in FIG.
It is a split (7) formed in two directions. Of course, the shape is not limited to the linear shape, and may be a substantially J-shaped shape as shown in FIG. 2 (E). Further, as shown in FIG. 2 (F), it may be implemented as a substantially T-shape. In FIG. 2 (G), a plurality of bent portions are formed and meandered. Also, in the sense of the original meandering, Fig. 2 (H)
Alternatively, the bent portion may be formed by a curved line as shown in FIG. The number of the bent portions is not limited to that shown in the figure, and may be appropriately selected. Further, as shown in FIG. 2 (I), the peeling portion (7 ') bordered by the split (7) may be stacked in two stages. Of course, the number of steps is not limited to two, and another number may be used as a plurality of steps (the peeling portion (7 ') is overlapped with a plurality of steps, so that the split (7) is formed in a meandering manner). The same is true for things). As an example of this application, FIG. 2 (J)
Due to the split (7) diagonally entering the
The one with (7 ') formed is shown below. What is shown in FIG. 2 (K) is a variation of the split (7) formed in a meandering manner, and the direction of the split (7) extending in a meandering manner is not limited to that described above. It indicates that it may extend in an appropriate direction. FIG. 2 (L) is a modification of the one shown in FIG. 2 (C), and has a part extending in parallel with the circumferential direction (X) at the tip of the split (7). As shown in FIG. 2 (M), the split (7) extends in a substantially Y shape. In FIG. 2 (N), the tip of the split (7) is formed so as to be wider than the other portions. The one shown in FIG. 2 (O) does not have the split (7) cut from the edge (2 ') of the roll (2), but the inside of the recess (6) is formed on the outer peripheral surface near the edge (2'). It has a small window (2 ″) that penetrates up to this. This small window (2 ″)
In this case, the peeling portion (7 ') is formed so as to extend along the circumferential direction of the roll (2). The split (7) may be carried out in a composite manner by selecting from the above-mentioned embodiments. Further, as shown in FIG. 2 (P), a protrusion (7 ″) is provided on a portion of the peeling tip portion of the peeling portion (7 ′) which bears the outer peripheral surface of the roll (2) to enhance the pressing effect. Good. This protrusion (7 ″)
Is more effective if it has elasticity. Further, in this case, the peeling portion (7 ') should be formed so as to recede from the outer peripheral surface of the roll (2) to the concave portion (6) side in a state where it is not biased by the pressing member (8). , Even more effective. Of course, if it is unnecessary, it is not necessary to adopt this configuration. On the contrary, as shown in FIG. 2 (Q), it is also effective to provide the projection (7 ″) on the rear surface of the peeling portion (7 ′), that is, on the surface facing the concave portion (6) side.

FIG. 3 shows a sectional view of a main part. The recess (6) is on the inner peripheral surface (9),
It is tapered and has a mortar shape. Pressing member
The taper corresponding to the inner peripheral surface of the recess (6) is also provided on the side (8). More specifically, the peripheral side surface (10) of the pressing member (8) is tapered so as to correspond to the inner peripheral surface (9) of the recess (6). With the above configuration, as the pressing member (8) advances to the recess (6), the (10) is recessed on the circumferential side surface of the pressing member (8).
The inner peripheral surface (9) of (6) is pressed and spread to fix the tubular body (1). Reference numeral (11) is a collar-shaped portion for preventing the tubular body (1) from coming off.

The inner peripheral surface (9) of the recess (6) and the peripheral side surface (10) of the pressing member (8) are both
Although the configuration with the taper has been shown, the invention is not limited to this, and only one of the recess (6) and the pressing member (8) may be tapered. Also, instead of tapering on either or both of the recess (6) and the pressing member (8), a curved surface may be provided at a corresponding position so that the pressing force is directed in the radial direction of the roll (2). Even if either the concave portion (6) or the pressing member (8) has a taper and the other has a curved surface, the same effect can be expected, and it does not hinder the construction as such).

Reference numeral (12) is a knob for rotating the pressing member (8).
Reference numeral (13) is a screw portion for fixing and sliding the pressing member (8) on the roll (2).
